Mike walked into his favorite pub and spotted his friend Paddy sitting alone, looking absolutely miserable.

“Hey, Paddy! What’s wrong with you?” Mike asked, taking a seat beside him.

Paddy sighed.

“Ah, Mike, I’ve just had a terrible argument with the wife!”

“Again?” Mike asked. “What happened this time?”

Paddy shook his head.

“I swear, that woman starts fights for absolutely no reason!”

Mike raised an eyebrow.

“Come on, Paddy. Surely something must have happened.”

Paddy leaned closer.

“Well, we were having a lovely evening. We’d enjoyed a nice dinner, everything was peaceful, and for once, neither of us was arguing!”

“Sounds promising,” Mike replied.

“It was!” Paddy exclaimed. “We went upstairs, things started getting romantic, and she began getting undressed.”

Mike nodded.

“Alright… so what went wrong?”

Paddy looked genuinely confused.

“Well, she took off her jeans, then her top, and I just asked her one simple, innocent question!”

Mike frowned.

“What question?”

Paddy sighed and said,

“I asked her, ‘Why are you wearing your sister’s bra?’”
